GPRS or 3G shield?

Hi,

I am looking for the most efficient, GPRS or 3G connectivity solution for Arduino...

Can someone recommend a solution that can be scaled in the future to a full production product?

Thanks!

Hi, I’ve searched a lot looking for a gprs shield. But after that I’ve realised you can’t do much with it, I found this amazing 3G module with lots of examples http://www.cooking-hacks.com/index.php/documentation/tutorials/arduino-3g-gprs-gsm-gps#step10

I didn’t buy it yet but I’m about to. It looks very useful, and easy to program.
